Trying to = choose replacement parts. Original geometry is okay - could use a few = tweaks. It seems Renner does not carry an exact match for the original = wippen. Their universal wip seems to work best. However, the flange is = shorter and causes the action spread to increase from the original 112.5 = to 115.5. However, I think I can just slide the wip rail back a few = millimeters to correct that. Below is a picture of the original at letoff. You can see that the jack = has lots of clearance between the knuckle and the felt at the back of = the jack slot. Below is a picture of the action with new parts. Here you can see that = the jack is touching the back felt and at the same time it is still = touching the knuckle. But if the whole wip moves back a few millimeters, = seems to me all will be fine. I would use a different wip heel to line = up better with the capstan - it seems this would work fine. The new = parts seem to regulate out just fine. Or is anyone aware of better matching replacement parts? Thanks. Terry Farrell ------=_NextPart_001_0008_01C59D17.A654C870 An HTML attachment was scrubbed...
